Buy Flow Meter Sanitary Supplier – SUP-LUGB Vortex flowmeter without temperature & pressure compensation – Sinomeasure Detail:

Measuring principle

A fluid flowing with a certain velocity and passing a fixed obstruction generates vortices. The generation of vortices is known as Karman’s Vortices.The frequency of vortex shedding is a direct linear function of fluid velocity and frequency depends upon the shape and face width of bluff body.

Since the width of obstruction and inner diameter of the pipe will be more or less constant, the frequency is given by the expression:

f=StV/d

In the formula:
f – Karman vortex frequency generated at one side of bluff body (Hz)
St – strouhal number (non-dimensional number)
V – average speed of fluid (m/s)
d – width of bluff body (m)
